p 1966 F. s. CARAVELLA ROLL SUPPORT MOUNTINGS Filed Aug. 9, 19 5 Ill 7INVENTOR FRANK S. CARAVELLA ATTORNEYS United States Patent 3,272,448ROLL SUPPORT MOUNTINGS Frank S. Caravella, 4321 N. 13th St., Milwaukee,Wis. Filed Aug. 9, 1965, Ser. No. 478,060 4 Claims. (Cl. 242--55.2)

My invention relates ot roll support mountings, and more particularly toa device for mounting the toilet paper roll support taught in my UnitedStates Patents Nos. 3,138,340 and 3,180,586.

The prime object of my invention is to provide a device that isextremely simple, and acts as the support for one end of the coilspring, for retaining the roll of toilet paper.

Another object of my invention is to provide a device that will adjustitself automatically for frictional contact with the inner surface of astandard adaptor, on a conventional toilet paper support.

Still another object of the invention is to provide a simple inexpensivedevice that may be applied by anyone Without mechanical skill, or theuse of special tools.

It is manifest to anyone familiar with replacing a roll of toilet paper,into a conventional holder, that by using a pliable coil spring tosupport the roll, no part of the assembly need be removed, and it is theprime object of my invention to provide a means rigidly supporting oneend of the coil spring which supports the roll of toilet paper, or thelike.

The device constituting my invention is a self contained assembled unit,that may be applied as an individual unit.

Other further objects of my invention will become more apparent as thedescription proceeds, when taken in conjunction with the drawings, inwhich:

FIGURE 1 is an enlarged front view of the sheet metal nut equipped witha plurality of outwardly extending members and an opening disposedcentrally therein;

FIGURE 2 is a cross-sectional view of the nut shown in FIG. 1, and takenat the line 2-2 therein;

FIGURE 3 is a similar view taken at the line 33 in FIG. 1;

FIGURE 4 is a vertical cross-section of the assembled mounting, with thenut shown in position as in FIG. 3;

FIGURE 5 is a similar view of the mounting, with the nut shown inposition as in FIG. 2;

FIGURE 6 is a top view of an assembled toilet paper support using myinvention to support the spring on one end, and in a normal operatingposition; and

FIGURE 7 is a similar view as shown in FIG. 6, with the roll of toiletpaper shown in phantom as being inserted onto the coil spring support.

Similar characters of reference indicate corresponding parts throughoutthe several views, and referring now to the same, the character 10 showsa sheet metal nut, having a centrally disposed aperture 11, equippedwith an outwardly extending slot shown as 12, which permits a radialformation shown as the tongue 13 when contacted by a thread.

The outer periphery of the washer, or nut 10, is equipped with aplurality of individual members spaced apart from one another byinwardly extending cut-out slots 14.

The plurality of individual members consist of three angularly shapedengaging members shown as 15, arranged at 120 in their relation to oneanother, three angularly shaped members 16 also arranged at 120 in theirrelation to one another and extending outwardly in opposite directionfrom the members 15, and six pointed members 17 disposed between themembers 15 and 16, and bent at an angle in the direction of the members15. All the members 15, 16 and 17 are separated from one another by theslots 14, as shown.

3,272,448 Patented Sept. 13, 1966 The attaching unit shown generally as18 (see FIGS. 4 and 5), consists of a threaded portion 19 spirallyrecessed at 20, to accommodate the tapered end of the spirally woundspring 21, a flange portion 22 recessed radially at 23, and a threadedbolt type portion 24. The portions 19, 22 and 24 constituting the unit18 are integrally constructed to form the unit 18.

The function of the attaching unit 18 is to engage the radial recess, orcavity 25, on one projecting support 26 of a conventional toilet papersupport shown as 27 (see FIGS. 6 and 7).

In applying my device constituting my invention, it is only necessary toinsert the washer, or nut 10, into the recess or cavity 25 in thesupport 26 forming a part of the conventional toilet paper holder 27,and after the spring 21 is applied to the spirally threaded portion 19of the attaching unit 18, the threaded bolt type portion 24 engages theaperture 11 of the washer 10, and the slot 12 will permit the tongueportion 13 to assume the contour of the threads on the outer face of thebolt type portion 24, and as the entire unit 18 is revolved by manualmeans, the screw portion 24, will cause the members 15 to engage thecircular recess 23, the angular members 16 to engage the inner surfacewall of the cavity 25, and the pointed members 17 to contact the beveledge 28 of the member 22, and the further the bolt assembly 18 isscrewed into the washer 10, the tighter the members 15, 16 and 17 willwedge into the cavity 25 for the support of the spring 21 to support theroll of toilet paper shown in phantom as 29 (see FIGS. 6 and 7).

The device is simple in construction and positive in its function, andalthough I have shown a specific construction and arrangement of theparts, I am fully cognizant of the fact that many changes may be made inthe form, shape and configuration of the parts and their arrangementwithout effecting the operativeness of the device, and I reserve therights to make such changes as I may deem convenient, without departingfrom the spirit of my invention, or the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent in the United States, is:

1. A sheet metal nut for associating the recess of a toilet paper holderwith an attaching unit for a spirally wound spring that supports toiletpaper, said attaching unit including a threaded portion for associationwith said spring member and a flange portion having a threaded portion,said flange portion being sized to engage the recess of said toiletpaper holder and being sized to be held in operable position withrespect to said toilet paper holder when the sheet metal nut isthreadedly associated therewith, said recess having a bottom and endsdefining the opening of said recess, said sheet metal nut comprising: acentral aperture for operable association of said nut with said threadedportion of said flange portion, a plurality of outwardly extendingengaging members including first engaging members, second engagingmembers and third engaging members, said firs-t members extendingoutward and in one direction and being interposed between said attachingmember and said recess to cause a friction fit therebetween when saidnut is operably associated with said flange, said second engagingmembers extending outward and in an opposite direction to said firstengaging members to frictionally abut against said recess when said nutis operatively associated with said flange, and said third attachingmembers extending outward and conforming to the contour of said flangewhen said nut is operatively associated with said flange, whereby saidattaching member engages said recess for rigid association when saidmetal nut is operatively associated with said recess.
